As an update (and to close the loop on my original post), the Blurb photoboook was really superb. Now, I have nothing really to compare it to however, so take that comment with a grain of salt. My wife loves it, and it has truly served its purpose.

We also are getting a photobook from our wedding photographer as part of the package, and I will be able to compare the quality of that book to the one that I made through LR from Blurb.
